First we find the slope m as follows:
So the equation is of the form:
y = 5x + b
When x = 1, y = 5. Therefore b = 0.
So the equation is:
y = 5x
So the equation is of the form:
y = 5x + b
When x = 1, y = 5. Therefore b = 0.
So the equation is:
y = 5x
Answer: b. 0.98
Step-by-step explanation:
The formula to find the maximum error of the estimated mean :
(1)
, where = standard deviation
n= Sample size
z* = Critical z-value.
As per given , we have
n=100
Critical value for 95% confidence interval = z*=1.96
Put these values in the formula (1), we get
Hence, the maximum error of the estimated mean quality for a 95% level of confidence is 0.98.
Therefore , the correct answer is b. 0.98 .
Answer:
$2,226.96
Step-by-step explanation:
You are going to want to use the compound interest formula, which is shown below.
<em>P = initial balance </em>
<em>r = interest rate </em>
<em>n = number of times compounded annually </em>
<em>t = time </em>
<em />
First, change 10% into its decimal form:
10% -> -> 0.1
Now lets plug in the values into the equation:
The final amount after 15 years is $2,226.96
